COMPAS (Correctional Offender Management Profiling for Alternative Sanctions) is a risk assessment used by the courts in some US states to determine the crime recurrence risk of a defendant.
The dataset [1]}) includes criminal history, time in prison, demographic data (age, gender, race), and COMPAS risk assessment of the individual. The dataset contains data of 6,172 defendants from Broward Couty, Florida.
The sensitive attribute in this dataset (the one on which the adversarial model will be biased) is race.
African Americans, whom biased model associates with a high risk of recidivism, represent \( 51.4 \% \)  of instances from the data set.
This set's target variable is the COMPAS score, which is divided into two classes: a high and low risk.
The majority class is the high risk, which represents \( 81.4 \% \)  of the instances.
